Regarding Basic Atom programming for Robot arm

Hi,

I am new to use robot arm. I have mini ssc III board with it which can be programmed with Basic atom. I have a program of another user.This program is used to move the robot arm in circular trajectory. I didn’t understand the function of a line:
serout 8,n96n,[255,0+speed,129]
I understood serout which sends serial output, 8 bits to send serial data, n96n which is N9600 baud rate. but i didn’t understand the function for [255,0+speed,129]. Can anyone explain the function, please. I was supposed to do another program after learning this example code but i was struck.

Please help me…

Thanks
regards
